RT Journal Article SR Electronic T1 Encephalopathy mimicking non-convulsive status Epilepticus JF Neurosciences Journal JO Neurosciences (Riyadh) FD Prince Sultan Military Medical City SP 52 OP 56 DO 10.17712/nsj.2018.1.20170214 VO 23 IS 1 A1 Nandhagopal, Ramachandiran A1 Al-Murshedi, Fathiya A1 Al-Busaidi, Mujahid A1 Al-Busaidi, Amna YR 2018 UL http://nsj.org.sa/content/23/1/52.abstract AB Primary hyperammonemic encephalopathy due to urea cycle disorders (UCD) typically manifests with episodic unresponsiveness and this clinical entity is not often included in the differential diagnosis of presumed non-convulsive status epilepticus (NCSE). However, this diagnostic consideration has therapeutic implications. In this report, we document the therapeutic importance of elucidating the specific cause of hyperammonemic encephalopathy that closely mimicked NCSE through 2 unique illustrative cases.
